Before You Begin

Before you install Veeam Backup & Replication, check the following prerequisites:

• A machine on which you plan to install Veeam Backup & Replication must meet the system requirements. For more information, see System Requirements.
• Veeam Backup & Replication must not be installed directly on a Hyper-V host. Such installation may lead to unpredictable system behavior. Instead, create a VM on the host and install Veeam Backup & Replication on the VM.

• A user account that you plan to use for installation must have sufficient permissions. For more information, see Required Permissions.
• Backup infrastructure components communicate with each other over specific ports. These ports must be open. For more information, see Used Ports.
• Veeam Backup & Replication requires Microsoft SQL Server deployed either locally on the backup server or remotely. If Microsoft SQL Server is not installed, the Veeam Backup & Replication setup will install it locally on the backup server. For more information, see System Requirements.

If Microsoft SQL Server is installed by the previous product version, Veeam Backup & Replication will connect to the existing configuration database, upgrade it (if necessary) and use it for work.

• You must remove Veeam Backup & Replication components of versions that are not supported by the upgrade procedure from the target machine. You may also need to remove earlier versions of other Veeam products and components.
